Beryllium

A relatively rare element of a huge industrial importance as one of Super Alloy components.

In its processed metallic form, Beryllium is one of the lightest and stiffest naturally occurring materials known to science; unfortunately, it is also highly brittle, making unalloyed Beryllium unsuitable for most industrial processes. However, Beryllium was discovered to be extraordinarily effective at absorbing neutron radiation, and has since become a key component in the construction of modern reactors and engines.
